good for late spring to early fall
Used this bag/liner on it's own so far and have been very happy. I have used all three ways of comfort and have slept well. Lowest night temps in this bag was about 50°f without a liner and was comfortable and preferred method of sleeping is draws only. Any lower may be a issue. The width of the bag is nice but let it be known that this bag does not have a hood(comes just over the shoulders). I'm 6'1" and I use the long. I do carry a StS liner just for that extra kick if needed.
